CELL-DOOR-LOCKIN DEVICE.

Specification of Letters Patent. at t 1, 9

Application filed May 17, 1915. Serial No. 98,185.

To all whom it may concern Be it known that I, EMILIO Ponno, a subjectof the King of Italy, residing at Albany, in the county of Alameda andState of California, have invented certain new and useful Improvementsin Cell-Door-Locking Devices, of which the following is a specification.

This invention relates to improvements in looking devices for cell doorsand more particularly an arrangement by which such doors may be openedand closed either singly or together from .a given station outside ofthe cell corridor.

. Another object of the invention is to so arrange the variousmechanisms that all parts are closed thereby preventing tampering by anunauthorized person.

Still another object of my invention is to provide means by which thedoors may be locked in their closed position and held in their openposition until released from the central operating point. 7

With these and other objects in view my invention consists in the novelconstruction, combination and arrangement of parts herein illustratedand more specifically pointed out in the appended claims.

Reference being had to the accompanying drawing forming a part of thisspecification,

Fig. 2 is an enlarged view in plan showing the mechanism associated withone door.

Fig. 3 is a view in section on 33, Fig. 2.

Fig. 4 is a view in section on 44, Fig. 2.

Fig. 5 is a view in elevation of one of the selector mechanisms by whichthe various doors are connected to the operating shaft. Fig. 5 is a Viewin elevation of one of the door latch-lifting devices.

Fig. 6 is a view in elevation of the member by which the lockingmechanisms are lifted and by which the same are locked when the door isclosed. 1

V Fig. 7 is a view in vertical section through the channel on one sideof each door showing the manner of locking the latter.

ig. 8 is a view in section through one edge of the door and the abutmentthereof.

, Fig. 9 a is an enlarged sectional view through the operating shaftshowing the yoke member. for imparting longitudinal movement to the saidshaft.

Fig. 10 is an enlarged view in plan of the end of the shaft by which thevarious doors are operated. Referring to corresponding parts in theseveral views by the same numerals of referenoe, 1 denotes the frontwall of a row of cells, the openings therein being closed by doors 2.These doors may be of any preferred construction and are provided withthe hangers 3 carrying grooved wheels 1 by which the doors are suspendedon a suitable track 5.

On the upper end of the hangers is mounted a strip 6 eXtending thelength of the door and provided with an inclined end 7 adjacent to whichis a notch 8 for the purpose hereinafter described.

Along one side of the door and forming an abutment for the latter is ajamb 9 formed of the U-section 10, and the web 11, the latter beingriveted or otherwise fastened. The cell wall projects into a rabbet inthe side of the door 2, thereby covering the crack be tween the door andits abutment. The portion 10 is provided with a slot 12 wherein is a bar13 having a limited longitudinal motion with respect to the member 9.The U-shaped portion 10 is provided with a transverse opening 14 throughboth walls, and the door 2 is provided with a hookshaped catch 15adapted to pass through this opening. This catch has an inclined facewhich may engage member 13, raising the latter, which then falls behindthe shoulder on the catch, thus holding the door in its closed positionuntil member 13 is again lifted.

Member 13 extends upwardly past the angle 5 which forms a track for thedoor and the upper end is provided with the lateral extension 16, theinside of which is, under certain conditions, adapted to drop into theslot 8 of member 6. When the extension is in this slot it will beapparent that the door is held in two places, at the upper portion byvirtue of 16 entering the slot 8 and at the center by means of theshoulder on the latch 15 being engaged back of the lower end of member13. A suitable guide 16 is provided at the upper end of bar 13 toprevent side bending thereof in case of attempts to force the door.

On the hanger 3 adjacent the inclined end of member 6 is provided abracket 18 having the forwardly projecting fingers 19 through the mediumof which the door is moved from its open to its closed position, andvice versa. The upper portion of the door and the associated mechanismis inclosed in a rectangular case, denoted in general by 20. This casebeing so arranged that the various mechanisms described are completelyinclosed, thereby preventing any unauthorized person from tampering withthe same. The front of this casing, denoted by 21, is longitudinallyslidable so that any portion of the mechanism is readily accessible.

Mounted in the front of the casing thus formed is a shaft 22 which isboth revolubly and slidably j ournaled at suitable intervals. On thisshaft for each door are keyed two members denoted by 23 and 2 1, theformer member being provided with means whereby all of the doors, or anyparticular door may be selected and moved longitudinally while thelatter has means whereby the latches of the various doors may be liftedwhen said doors have been selected for opening, but capable ofpreventing the raising of the latches of those doors which have not beenselected. Each of the members 23 is shown as provided with a conicalshaped portion 25, a cylindrical portion 26, and a collar 27, but theshape is ii'nn'iaterial, being a mere structural detail. The collar 27is provided with two wards 28 and 29. The wards 28 on all of the members23, project from said members at the same angle, but the wards 29project at different angles, the former being used when all the doorsare opened sin'iultaneously, while the latter is used to selectivelyopen any individual door.

WVhen the door is in its closed position the collar 27, together withits ward, are spaced between the fingers 19 but the distance betweenthese fingers is such that the collar has some travel before the wardsengage the fingers 19. Member 241 is provided with two projecting lugs30 which for any door are spaced in the same angular relation as thewards 28 and 29 of that door, and each of these lugs is provided withthe inclined faces 31 adapted to contact with the underside of the hook16. Also above these locks is a shoulder 32 which when the doors are allto be held closed may be brought into contact with the top of hook 16,thus preventing the latter from being raised.

The strip 6 is provided with an additional notch 36 and pivotallymounted to one side of the door is a latch 37 extending outwardly fromthe wall and normally resting on the tooth sprocket gear 42 keyed on thesame shaft with lever 40, this sprocket being connected by means of achain in a tooth gear 4 1, mounted on a square shaft 45. This shaft ispivotally mounted in a bearing bar a6 and extends into a square openingin the end of shaft 22, whereby the latter is slidable on shaft 45 butis rotated by the latter.

The end of shaft 22 is provided with a grooved collar 46 about'which isa yoke 17, this yoke being slidably mounted on a bar a9 positionedparallel to shaft 22 and being provided on the underside with ears 50between which is pivotally mounted the lever bar ell. The latterpivotally mount ed to the frame-work of the cells as shown at 52 andworking over a stationary segment 53. Adjacent the lever 41.15 a toothsegment 54:, each tooth corresponding to a given operative position ofshaft 22.

I'laving thus described the various details of my invention itsoperation isas follows First, if a given door is to be opened, lever 40is moved until the pawl drops in the notch corresponding to that door.Then through the chain 4-3, sprocket -24 is rotated, turning with it theshaft 22 so as to bring the ward 29 of the selected door into alinementwith the fingers 19 of that door. At the same time the member 30, inalinement with ward 29, is positioned underthe hook 16 of that door, thehandle 41 is then moved so as to slide the shaft 22 longitudinally, thefirst movement of the shaft causing the inclined faces of member 30 toraise the hook 16 and thereby the member 13, which in turn lifts thismember from. the notch 8 and from back of the shoulder on catch 15.

During this lifting movement the ward 29 has been moving from one finger19 to the other so that by the time the door is released the ward hascontacted with the second finger 19 thereby moving the door in thedirection of the arrow, which movement is continued as long as leveralis rotated. A stop is provided for the door so in its extreme leftposition the notch 36 is positioned under the latch 38. Thus if it isdesired to have the door held in its open position lever 10 is againrotated to its extreme position whereby the wards clear the fingers 19thus allowing the shaft to be moved to the right without carrying thedoor with it and as the member 23 is moved from under the bar 37, thelock on the latter drops into the notches 36 and thereby holds the dooragainst being closed. ,In closing the door, lever 41 is shifted in theopposite direction, causing member 30 to lift latch 37, after which thedoor moves to closed position.

If it is desired to open all the doors simultaneously, handle 40 isrotated to the position in which the wards 28 aline with thecorresponding finger 19 of each door so that when the handle 41 is movedto slide to the door longitudinally, all doors are opened. The doors areclosed by the opposite move of handle 41, and after being closed theshaft 22 is rotated to the position where the wards clear the fingers ofall doors. When the handle 40 is again moved, the position is reached toimpart to the shaft a slidably longitudinal movement whereby theshoulder 32 is brought over the top portion of hook 16. The handle 41 islocked in this position by means of a suitable pawl and slotarrangement, and in this manner it will be impossible for the latch bar13 to beupraised.

While I have shown and described the preferred embodiment of myinvention it will be understood that minor changes may be made in formand detail without departing from the scope of th claims.

' l Vhat I claim as new and wish to cover by Letters Patent is 1. Thecombination with a plurality of sliding doors, a shaft slidably androtatably mounted above said doors, selectors attached to said shaftadjacent each door, wards on said selectors, fingers extending from saiddoors, means for rotating said shaft to bring the wards into engagementwith said fingers, and means for longitudinally shifting said shaft toimpart movement to the door by means of the engagement of the wards andfingers.
